Going to start the house remodel probably beginning in May (waiting for temps to come up a little). Anyway the house is plaster and lath. I removed a small portion of an upstairs area last fall to add a 3/4 bath. I had put up temp plastic walls to keep the dust from the rest of the house. My shade tree dust fan how ever didnt work out so well. I put 2 furnace filters in front of a box fan and exhausted out a window. The dust was fine enough to pass through the furnace filters and after 4 days the fan motor was clogged up and burned up.
I thought my idea would work as when I was a remodel carpenter out of high school we used the same method in large remodels of building at U of M. In that case though we built filter walls and used 2 24″ fans behind the walls. We did oil the filters though. And I did not do that on my small version.
Being out of the trades for 15 years now (aircraft mechanic since then). Is there something decent to use for a homeowner? Product made for this? Same idea but use better quality fan and or filters? Ideas?

Use pleated paper filters instead of fiberglass ones, and get as much filter area (and hence slowest airspeed at the filter) as you can manage.
Doh, never though of paper filters. I was using fiberglass mesh ones.
Thanks.
Fiberglass mesh ones have huge holes in them. I think the fiberglass ones are for people who wnat to put a filter in but never want to change it. They really don't stop much.
Skip the filters.
Buy the cheep fans at depot for 20 bucks. If they tank who cares.

I actually picked up 4 at a salvage place that buys overstocks and merchandise from places closing down for $7 a piece. Should have picked up more.
rental places have huge $#@#$!! fans that move mucho CFM's and you can see the dust moving towards the fan. They are very loud though but they really clear the air and may be only use them during the demo stage?
I second the cheap fan no filter route. I blow the motor out occasionally with the compressor, have 2 going strong for 5+ years.
